My primary use of Publisher would be to design scientific figures/posters. For the most part, this involves arranging plots and graphs generated externally.
The catch is this: these plots/graphs will be updated (e.g. by rerunning the code that generated them) quite frequently.
I did find the setting in the preferences to auto-update linked resources but AFAIK I still have to manually switch each image to "link" via the Resource manager. Having the option to import images as links by default (could be a document- or program-wide setting) would be really helpful.
This a very common workflow in science and having this functionality would make Publisher very attractive for a lot of labs.
Thanks & Keep up the good work!
